Find the area of the circle x^2+y^2=16 by the method of intregration
zhuklara [117]

Answer:

Hello,

16\pi

Step-by-step explanation:

I=\dfrac{Area}{4} =\int\limits^4_0 {\sqrt{16-x^2} } \, dx \\\\Let\ say\ x=4*sin(t),\ dx=4*cos(t) dt\\\\\displaystyle I=\int\limits^\frac{\pi }{2} _0 {4*\sqrt{1-sin^2(t)} }*4*cos(t) \, dt \\\\=16*\int\limits^\frac{\pi }{2} _0 {cos^2(t)} \, dt \\\\=16*\int\limits^\frac{\pi }{2} _0 {\frac{1-cos(2t)}{2}} \, dt \\\\=8*[t]^\frac{\pi }{2} _0-[\frac{sin(2t)}{2} ]^\frac{\pi }{2} _0\\\\=4\pi -0\\\\=4\pi\\\\\boxed{Area=4*I=16\pi}\\

Resolving inequalities 6/5x-12&lt;2-3/2x
Anna007 [38]

Answer:  x < \frac{140}{27}

<u>Step-by-step explanation:</u>

\frac{6}{5}x - 12 < 2 - \frac{3}{2}x

10(\frac{6}{5}x - 12) < 10(2 - \frac{3}{2}x)

2(6)x - 10(12) < 10(2) - 5(3)x

 12x  -   120  <   20  -  15x

<u> +15x             </u>     <u>        +15x </u>      

 27x   - 120  <   20

<u>          +120 </u>    <u>+120</u>

27x              <  140

            \frac{27x}{27} < \frac{140}{27}

              x < \frac{140}{27}
